My Cluster is faded and rather well aged since I have a 1982 vintage car.... I kind of like the look as it reminds me of an old clock face.... Eventually if I have a failure in there I will have to go in and make a repair.... I may do some cleaning and minor painting but I kind of like the "patina" that the cluster has developed over the years..... Cars are kind of funny because with any other collectable because cleaning and painting them does not kill their value like it would with an antique piece of furniture or clock.... A friend of mine who does clock repairs put a set of clock hands in his ultrasonic cleaner and discovered they were gold rather than brass and became rather shiny.... The owner of the clock was not very happy with the clean hands.....
